Pinpoint Tests RJ: REDUCTANT Tank Level: Introduction

WARNING: This page is about a different variant/trim than selected.

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

This pinpoint test is intended to diagnose the following:

reductant level sensor
harness circuits: CAN2+, CAN2-, GND, RDL1, RDL2, RDL3, SIGRTN and VPWR
reductant dosage control module (5H298)
PCM (12A650)
